Abstract (en)
An industrial fabric used in the manufacture or processing of at least one material web includes a base fabric having a board side and a machine side. The base fabric includes a plurality of spirals extending in a cross machine direction (CMD). The spirals are interconnected together with each other along adjacent peripheral edges to form a spiral link fabric. The base fabric has opposite lateral side edges extending in a machine direction (MD). One or more electrostatic control yarns are positioned within a corresponding spiral and extend in the CMD direction to the lateral side edges. A pair of conductive edge coatings are applied to at least the board side of a respective lateral side edge for a predetermined width. The conductive edge coatings and the one or more electrostatic control yarns form an electrostatic grid. A pair of wear resistant coatings are applied to an area adjacent a respective conductive edge coating such that a substantially constant spacing between the wear resistant coatings corresponds to a minimum expected working width of the industrial fabric. The wear resistant coatings are wear resistant with a hardness of between approximately 50 to 66 Shore A Durometer Hardness, and a coefficient of friction greater than approximately 2 on the board side. The industrial fabric has a completely non-marking seam because of its integral nature with the base fabric and the equal amount of the wear resistant coating at the seam and the edges.
